ETE ORLANDIA Wastewater Treatment Plant, Orlândia, São Paulo, Brazil

ETE ORLANDIA is a municipal wastewater treatment plant located in Orlândia, within the state of São Paulo, Brazil. The facility serves an estimated population of 40,875 residents, classifying it as a medium-sized agglomeration under Brazilian sanitation standards. The plant is situated in the southeastern region of Brazil, an area characterized by intensive agriculture and urban development. As a plant serving a medium-sized population, ETE ORLANDIA is expected to comply with Brazil's national environmental standards, including CONAMA Resolution 430/2011, which sets effluent discharge limits. Plants of this scale typically employ secondary biological treatment to meet regulatory requirements. The facility's operational status and capacity details are managed by the local sanitation authority. The treated effluent from ETE ORLANDIA is discharged into local water bodies that are part of the Paraná River basin, one of South America's major river systems. The downstream environment includes the Rio Grande and eventually the Paraná River, which supports diverse aquatic ecosystems and provides water for agricultural and urban use. Proper treatment is essential to protect water quality in this ecologically and economically important region.

The plant's treated effluent enters local streams that flow into the Rio Grande, a major tributary of the Paraná River. The Paraná River basin supports extensive biodiversity, including migratory fish species and riparian forests. Downstream, the river feeds the La Plata River estuary, a critical habitat for aquatic life. Effective wastewater treatment helps prevent nutrient pollution and maintains water quality for downstream communities and ecosystems.
